Looking for a platformer that'll bend your brain a bit? AlterEgo: DreamWalker is the 8-bit-on-acid sequel to AlterEgo, and basically just builds on its predecessor. More levels, arguably trippier visuals, and the same switch-up platforming action of the original. The game mechanic, by the way, is simple, but fairly novel: you move your character around the platform world, but on the opposite side in a mirrored position as an 'AlterEgo' (the ghost-looking thingy).
